Across the UK, scam phone calls have evolved from the occasional nuisance to a full-blown national threat. From local fraudsters impersonating utility companies to sophisticated international crime rings running global phone scams, the danger is real—and rising.
According to the UK Finance Annual Fraud Report 2023, criminals stole £1.2 billion through fraud in 2022, with impersonation scams—often initiated by phone—remaining one of the most damaging forms of attack.
For households looking to defend themselves, call blockers have become an essential first line of protection. These simple yet powerful devices stop scammers before they reach your ears—helping to disrupt fraud attempts, protect your finances, and give you back peace of mind.

Understanding the Threat: Local and Global Fraudsters
Phone scams have become a widespread issue across the UK, targeting households with increasingly sophisticated tactics. From local con artists to international crime rings, these fraudsters use fear, urgency, and deception to exploit unsuspecting individuals. Recognising common types of scam calls is the first step towards protecting yourself and your loved ones.
Spoofed HMRC or Bank Calls
Scammers impersonate HMRC or high-street banks, claiming urgent tax debts or suspicious account activity. Victims are pressured into making immediate payments or sharing personal information.
Energy Rebate Scams
Fraudsters pose as representatives from Ofgem or local councils, offering fake rebates or grants linked to the energy crisis. These calls often request bank details under the guise of processing payments.
International Investment Scams
Global fraud rings target UK residents with promises of high-return investments in cryptocurrency, bonds, or foreign real estate. These are often complex, well-rehearsed operations with fake websites and documentation.
Tech Support Cons
Scammers claim to be from major tech companies like Microsoft or BT, warning of security issues or viruses. They then persuade victims to allow remote access to their devices or install malicious software.
Parcel Delivery and Courier Scams
Automated messages or callers pretend to be from Royal Mail, DPD, or courier firms, claiming a missed delivery or customs fee. Victims are directed to fake websites to enter payment and personal data.

How Call Blockers Disrupt Scam Operations
1. Filtering Known Scam Numbers
Modern call blockers—like CPR Call Blocker—come pre-programmed with thousands of known nuisance numbers, including those flagged by Ofcom and Action Fraud. These are automatically blocked, meaning many scam calls never even ring your phone.
2. Blocking International Numbers
A large portion of fraud now originates from overseas. Call blockers allow users to block entire country codes or restrict calls to UK-based numbers only, preventing international fraud rings from gaining access to your landline altogether.
3. Stopping Robocalls and Auto-Dialers
Many scams begin with a recorded message or automated system. Call blockers use technology that filters out robocalls before they can connect, breaking the cycle before it starts.
4. Custom Control: One-Click Blocking
Most blockers, including CPR models, feature a “Block Now” button—so if a scam or nuisance call does get through, users can stop that number from ever calling again with a single press.
5. Disrupting Scam Economics
Fraud operations rely on volume: the more calls they make, the more likely they are to catch someone unaware. Call blockers cut into that model by shrinking the pool of reachable targets. With fewer people answering scam calls, the business model becomes less viable—especially at scale.
